The present invention has forits principal object to provide asimply-constructed lens mounting of the general character and con?struction hereinafter more fully set fortln] in which the parts havebeen reduced to a minimum, the device being easily appliedito lensesofvarying thickness, without chang- 'ing or. disturbing the parts of,the mounting i isia central sectional representationof the partsllustrated in said Fig. 1,'showing thei lens' firmlyfmounted andsupported by the stud; "Fig; 3 is a similar sectional Patented No v3,1914; I

S'imilar. characters otreference are'em-- ployediniall of saidabove-described views,

towin dicate corresponding parts. i

Pteferringnow to the figures of theidraw ings," the reference-character"1 indicates the usual lens provided near its marginal edgeportion andupon the major {axis of the lens j vit hfa post-receiving hole 2.Arranged vin screwed ajscrew-threaded nut-like member this'hole is apost 3 which is formed with a screwthreaded portion 4: projecting beyondthe surface 5 of 'the lens' and upon :whichis connected with' theportion? 015 said post '3, and-integrally united-therewith, is asuitably shaped fiattenedfiout member 8,

forming a pivot-plate extending substan tiallynina plane atfa rightangle totheiaxis foffs aid post 3; This pivot-plate is slightlyangularly'bent, as at-'9, see Figs.= 2and13 of the drawings, so'asltoextend slightlyaway from'the surfacelO of the lens, said'iangularportion being alsofprovided Jnear its free end-portion ll lwithasuitably formed hookreceiving perforation or hole, as 12, for thepurposes to be presently more fully described, When the post 3 isinserted in the hole orperforation 2 in the lens, the pivotplate andsaid post are rigidly fixed in posi tionfby screwing thenut-likemember 6down upon the screw threaded portion 4 of the post 3 andupon the surface5 of lens, as shown in saidFigs. 2 and 3.

The combined. pivot-plate and post are preferably made a single pieceofwire of the proper. gage, the part 8, being bent at the proper angle to;the part formingfthe post 3, and being suitably flattenedout in a Thereference-character 13, in Figs. 1 to 7 inclusive, indicates a stud withwhich are integrally connected the arcshap'ed strap members or elements14 which are adapted to be fitted upon and engage the adjacent edge ofthe lens. The stud is also: further provided with the flanges 15 betweenwhich are arranged in the usual manner, the endportions of thenose-bridge 1G and the noseguards 17, the said end-portions beingsuitably secured in position by means of a screw 15 18, or any othersuitable fastening means. Extending from the lower edge-portion of theinner flat surface 19 of the stud 13, is a suitably formed hook or lug,as 20, adapted to beinserted in the perforation or hole 12,

2o hereinabove mentioned. and in alinement from the upper edge-portionof said flat surface 19 is a forwardly extending holding plate-likemember or element, as .21, adapted, to bearranged upon the flat surface5 of the lens, and haying its front end-portion preferably made muchthinner than the 'remaining portion of said plate-like member or element21, said thin end-portion being so pronged or bifurcated, as at 22, allbeing adapted to be arranged above the, element 4 ofthe post 3 andembracing that portion of the post 3 above said element 6, in the mannerclearly represented said Fig. 2 of the drawings. Suitably secured uponthe upper 'surface of saidplate-likeme1iiber or element 1 p 2.1, bymeansof a pin, rivet, orscrew, as 23, or by means of any other suitablefastening means, is a holding catch 24:, made in the 40 form of -aresilient spring-plate'or finger, the free end-portion of which, whenthe hook or lug Q'Ohas been insertedin the hole l9. and is pivotallymoved in the directionj of the arrow y, see.Fi'g.- 3, passes over thefree end-portion of the post 3', whereby a hole 'orlperforation 25 insaid resilient spring-plate or catch 24 is" brought directly.

over the end of the said post, sothat the said post enters the hole orperforation 25 ;:and,

with the said spring-plate or catch 24 snap; ping into holdingengagement with the post 3,. it will be clearly evidentthat' the stud 13and lens 1 will be securely connected with relation to each other, butmay beyjust as readily separated when the spring-plate or catch 24: israised into the dotted position indicated in said Fig. 2, and wherebythe stud can be swung into the position shown in Fig. 3 of the drawings,and readily separated from its holding engagement with. the flat plate8, so thatthe lens and stud will be brought into their separatedrelation, aswill be clearly understood from an inspection of said Fig.3. To prevent the hook or lug 20 p from entering too far into the holeor perfora-tion 12, and thereby perhaps interfering with the pivotalmovements of the parts, the hook-element or"lug 20 is preferably madewith a pair of ofi-sets or shoulders as 26, which cooperate with thepart 11 of the fiat plate 9,- as will be clearly evident.

The operation of the device or mechanism in bringing the stud and lensinto their snapped engaged relation, and the manner of separating thestud and lens will be fully understood from the foregoing description,and from an inspection of the severalfigures of the drawings, andneednot, for that reason, be furtherdescribed.

Instead of making the combined pivot- 0 plate and post 3 from wire, inthe manner herein-above stated, itmay be made from a flat piece ofsheet-metal of the general configuration represented in Fig. 8 of thedrawings, the same comprising the pivot-plate with said hook or lug 9.0and extending part 27 with which is connected, by means of a narrowneck-portion 28, an extension, as 29. Thisextension is bent, atsaidneckportion28, at an angle to the plane of the part 27, andtheextension is curled in a manher so as to form a tubular post, as 30,see

Fig.9, which is also provided with a screwthreaded portion for thepreviously men tioned nut-like element. The construction and operationof the remaining parts ofthe eye-glass mounting,-as will be seen from aninspection of saidFig. 8, is the same as that described in connectionwith the construc- .struction of the said parts, comprising my noveleye-glass mounting, without departing from the scope ofthe invention asdescribed in the foregoing specification, and

as set forth in the appended claims. Hence, I do-not limit myinvention'to the exact arrangements and combinations of the severaldevices and parts, as described in the said specification, nor do Iconfine myself to the exact details of the construction of the saidparts as illustrated in the accompanying drawings.

' .I claimP- a -1. In eye-glasses, combination with a lens,a combinedpivot-plate and post made from single piece, said plate being locatedupon one sideof the lens, and the post extending through the lens, andmeans upon said post for rigidly securing the combined pivot plate andpost to. said lens. v 2.
